Hi Bert,

I'm trying to write a logging facility for send (sample work for Prof.
Hirschfeld, actually): Each time a message is sent, the target class,
message and a couple of other properties should be logged.

That means I have to open a file upon initialization and write the file
at each send. There's no other way than to do that in the Interpreter,
as far as I can see.
